In R2012b, when you close the last tab in Editor or Variables window, the window itself closes. Is there a way to have it the old way, the last tab closes but the window stays opened?
Oh, the old Matlab 6 behavior again. I was happy, that my R2009a does close the editor, when I press its close button, and not when the editor smartly thinks that there is nothing to do anymore. I'm convinced, that only the user can decide, if the editor should be closed or not.
